Abstract
The utility model discloses a minute wheel of a quartz clock, comprising a big gear, a small gear and a U-shaped leaf spring. The small gear is composed of gear teeth, a gear shaft and a limit plate; wherein the upper end faces of the small gear teeth are connected with the gear shaft into a whole body, and the lower end faces of the small gear teeth are connected with the limit plate into a whole body. A hole is arranged in the middle of the big gear and is arranged in the small gear downwards along the small gear shaft and is positioned above the small gear limit plate. The leaf spring is cushioned between the big gear and the small gear. The leaf spring is used between the big gear and the small gear of the minute wheel for fixed connection, therefore the mutual contact of the big gear and the small gear is not too tight or too loose for achieving the purposes of convenient time regulating to the quartz clock and guaranteeing the precise travel time of the quartz clock under the elastic regulation of the leaf spring when the material of the big gear and the small gear of the minute wheel expands or shrinks due to the theory of expansion with heat and contraction with cold in the working environment under different temperature or in different seasons.
Description
Technical field
The utility model relates to a kind of crystal clock, particularly a kind of improvement of crystal clock minute wheel.
Background technology
Crystal clock is one of indispensable daily necessities in people's daily life, big now to the market, the wall clock that office hangs, the little wrist-watch of wearing on hand to people, all adopt mostly with the clock and watch of crystal clock as the table movement, this is owing to crystal clock does not take the reason of often winding up as traditional mechanical clock, particularly for the busy day by day people of work, it is often thing that absurd note is wound up, this has influenced the use to clock and watch greatly, and crystal clock can be in the long time, just under situation about needn't wind up, when guaranteeing normally the walking of clock and watch, be subjected to user's welcome for this reason.The minute wheel of the crystal clock of prior art adopts separate type, the gear wheel and the pinion wheel that are it are (as shown in Figure 1 to Figure 3) that is divided into two parts, this is because the needs the during school determine, pinion wheel includes the gear teeth, wheel shaft, boss with the level, the upper surface of the wheel shaft and the gear teeth joins and forms one, the wheel the tip of the axis is used for fixing and connects minute hand, the lower surface of the gear teeth and boss with the level join and form one, the boss of pinion wheel tightly is embedded in set hole, gear wheel middle part, the friction force that big pinion wheel is passed through each other forms interlock, when walking in the process, second hand wheel is meshed with the second hand third wheel, the second hand third wheel is meshed with the gear wheel of minute wheel, the rotation of second hand wheel has driven the rotation of minute wheel, and the rotation of the gear wheel of minute wheel makes with the pinion wheel of the minute wheel of its tight mutually embedding and rotates together, and the pinion wheel of minute wheel is meshed with the minute hand third wheel, the minute hand third wheel is meshed with hour wheel, and the rotation of minute wheel has driven the rotation of hour wheel; When walking, error occurring, at this moment need to come proof time by rotation timing knob, the power wheel of timing knob is meshed with the minute hand third wheel, the rotation of timing knob drives the minute hand third wheel and rotates, the rotation of minute hand third wheel drives the rotation of the pinion wheel and the hour wheel of minute wheel simultaneously, reach the effect of timing, this moment is owing to be the separate type structure that is nested between the pinion wheel of the gear wheel of minute wheel and minute wheel, the rotation of minute wheel pinion wheel does not drive the rotation of minute wheel gear wheel, be for clutch mutually between the gear wheel of pinion wheel and minute wheel of minute wheel, with the minute wheel gear wheel mutually the second hand wheel of transmission then can not rotate yet, because between the minute wheel gear wheel of prior art and the minute wheel pinion wheel is the structure that is nested, based on the principle of expanding with heat and contract with cold, expand because of material is heated when summer or under the higher environment of temperature between the gear wheel of minute wheel and the pinion wheel of minute wheel, it is tighter that it is in contact with one another; Shrink and catch a cold because of material when winter or under the lower environment of temperature, make it be in contact with one another pine, this just causes under the high situation of temperature easily and assembles clock and watch, catch a cold because of material when use in the low place of temperature and shrink, cause the minute wheel gear wheel to contact pine with the minute wheel pinion wheel, error can occur when walking; Assemble clock and watch under the low situation of temperature, expand because of material is heated when use in the high place of temperature, it is tighter to have caused the minute wheel gear wheel to contact with the minute wheel pinion wheel, during timing because of the bad accent of tension.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, and providing a kind of can make things convenient for by timing, can guarantee the minute wheel of the crystal clock of degree of accuracy when crystal clock is walked again.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of minute wheel of crystal clock, comprise gear wheel, pinion wheel, spring leaf, pinion wheel is made up of the gear teeth, wheel shaft, banking stop, the upper surface and the wheel shaft of the pinion wheel gear teeth join, the lower surface and the banking stop of the pinion wheel gear teeth join, and a hole is established at the gear wheel middle part, and its hole is inserted in pinion wheel downwards along pinion shaft, and place on the pinion wheel banking stop, the spring leaf liner is between gear wheel and pinion wheel.
The upper surface of the described pinion wheel gear teeth and wheel shaft form one.
The lower surface of the described pinion wheel gear teeth and banking stop form one.
Described banking stop is circular, and its circle footpath is greater than the aperture in set hole, gear wheel middle part.
The tooth footpath of the described pinion wheel gear teeth is less than the aperture in set hole, gear wheel middle part.
Described spring leaf is the U-shaped spring leaf, and the two ends of spring leaf is provided with barb.
Be provided with groove between the described pinion wheel gear teeth and the banking stop.
The liner of described spring leaf is the both sides of spring leaf U-shaped, embeds groove and is fixed by barb.
The utility model is to realize like this, the hole of the gear wheel wheel shaft along pinion wheel is inserted in downwards, gear wheel is placed on the pinion wheel banking stop, because the tooth of pinion wheel gear teeth footpath is less than the aperture in set hole, gear wheel middle part, the pinion wheel gear teeth are on the gear wheel, and the groove that is provided with between the pinion wheel gear teeth and the banking stop is revealed between the pinion wheel gear teeth and the gear wheel, the embedding of U-shaped spring leaf is pressed into groove, and utilize the barb on the spring leaf two ends to hook fixing, gear wheel is pressed on the pinion wheel banking stop by spring leaf, has realized connecting between minute wheel pinion wheel and the gear wheel.
The beneficial effects of the utility model are, because having adopted spring leaf that it is interfixed between the pinion wheel of the gear wheel of minute wheel and minute wheel connects, in different seasons or under the working environment of different temperatures, when the material production expansion of the gear wheel that causes minute wheel because of expanding with heat and contract with cold and the pinion wheel of minute wheel or the variation of shrinking, under the flexible adjustment of spring leaf, its be in contact with one another can not cause too tight or too loose, reached and to make the crystal clock timing convenient, the purpose of degree of accuracy in the time of can guaranteeing the walking of crystal clock again.
